Introduction
Maintenance
Before using the instrument, read and follow the following maintenance instructions:
18
•
Do not leave the instrument in direct sunlight or in a closed vehicle for
prolonged periods. Overheating the instrument may reduce its efficiency.
•
If the Trimble M3 DR series instrument has been used in wet conditions,
immediately wipe off any moisture and dry the instrument completely before
returning the instrument to the carrying case. The instrument contains
sensitive electronic assemblies which have been well protected against dust and
moisture. However, if dust or moisture gets into the instrument, severe damage
could result.
•
Sudden changes in temperature may cloud the lenses and drastically reduce the
measurable distance, or cause an electrical system failure. If there has been a
sudden change in temperature, leave the instrument in a closed carrying case in
a warm location until the temperature of the instrument returns to room
temperature.
•
Do not store the Trimble M3 DR series instrument in hot or humid locations. In
particular, you must store the battery pack in a dry location at a temperature of
less than 30 °C (86 °F). High temperature or excessive humidity can cause mold
to grow on the lenses. It can also cause the electronic assemblies to deteriorate,
and so lead to instrument failure.
•
Store the battery pack with the battery discharged.
•
When storing the instrument in areas subject to extremely low temperatures,
leave the carrying case open.
•
When adjusting the leveling screws, stay as close as possible to the center of
each screw’s range. The center is indicated by a line on the screw.
•
If the tribrach will not be used for an extended period, lock down the tribrach
clamp knob and tighten its safety screw.
•
Do not use organic solvents (such as ether or paint thinner) to clean the
non-metallic parts of the instrument (such as the keyboard) or the painted or
printed surfaces. Doing so could result in discoloration of the surface, or in
peeling of printed characters. Clean these parts only with a soft cloth or a tissue,
lightly moistened with water or a mild detergent.
•
To clean the optical lenses, lightly wipe them with a soft cloth or a lens tissue
that is moistened with alcohol.
Trimble M3 DR Series Total Station User Guide

Applying power
•
Plug in the charger to the supplied AC adapter to turn the unit on. The power
input must be 5 V with at least 4 A of current capability. Each battery may take
up to 2 A while charging.
Charging a battery
24
•
Simply slide a battery into either battery slot to begin charging. The adjacent
charge indicator will illuminate yellow when charging is in progress. The charge
indicator will change to green when charging is complete.
•
Charger slots are completely independent so a battery may be inserted
regardless of the state of the other battery slot.
•
Charging may take 2-4 hours if the battery was normally discharged.
•
Charging may take up to 5 hours with a completely drained battery which has
been stored for several months without use.
•
By design Li-Ion batteries should not be charged above 40 °C-45 °C so a blinking
charge light may mean the batteries are too hot for charging. Charging will
resume after the batteries cool down. The charging time will be longer due to
the batteries cool down when charging batteries above 40 °C-45 °C.
Trimble M3 DR Series Total Station User Guide
Preparation
•
2
If the charge indicator(s) are blinking and the batteries feel cool, it may indicate
a problem with the battery or the charger. If the charge light is still blinking after
trying several batteries which are not warm, there is a problem with the unit or
the batteries themselves.
Conditioning / calibrating a battery
•
Battery calibration is necessary about once every 6 months or more often if
desired. Calibration insures the reported battery charge remaining is accurate.
•
Hold down the calibration button on the unit and then insert a battery while
holding the calibration button to begin a battery calibration. Only the battery
which was inserted while the button was depressed will begin calibration.
During a battery calibration the battery will be charged, discharged completely,
and then recharged before finishing. Calibration should complete in roughly 17
hours and the charger vents should not be covered during a calibration cycle.
•
The blue calibration indicator light(s) will blink slowly (on 1.5 sec, off 2 sec) while
a calibration is in progress and the charge light(s) may be on or off during the
calibration cycle.
•
When a calibration cycle is completed, the calibration light will stop blinking
remain on until the corresponding battery is removed.
•
The bottom case temperature may continue to climb up to approximately 43 °C
before temperature regulation is enabled to keep the case from getting warmer.
As the battery voltage drops, the case will cool down and the automatic
temperature limiting will no longer be necessary which minimizes the time it
takes to discharge a battery.
•
If the case temperature continues to get too hot internally even after
temperature regulation is enabled, there is a secondary failsafe which will abort
the calibration completely. If an abort occurs, the calibration light(s) will blink
rapidly and battery charging will be re-enabled.

The final turn of the tangent screw should be in a clockwise direction, to
align the target accurately on the center crosshairs.
Setting the measurement mode and preparing the target
The Trimble M3 DR series total station has two measurement modes: Prism mode
(Prism) and Reflectorless mode (N-Prism). These modes can be changed at any time by
holding down the [MSR1] or [MSR2] key for one second.
To set the measurement mode depending on the target you want to measure, see the
following table.
Target
Target setting
Prism, reflector sheet
Prism (Prism mode)
Other (reflective materials)
N-Prism (Reflectorless mode)
In some cases, you can measure another target that is not appropriate to the set
measurement mode.
Note – The Trimble M3 DR 2'' total station is Laser Class 3R in the Reflectorless mode and
Laser pointer function, and Laser Class 1 in the Prism mode.
Do not sight the Prism when the Laser Pointer is on.
Note – The Trimble M3 DR 3'' and 5'' total stations are Laser Class 1 in the Prism and
Reflectorless mode, and Laser Class 2 in Laser pointer function.
21.1
Measurement with a prism
Do not use a prism with scratches, a dirty surface, or a chipped center. Prisms with thin
edges are recommended.

As the Trimble M3 DR instruments are extremely sensitive, multiple reflections on the
prism surface can sometimes cause a significant loss in accuracy.

To maintain the accuracy of your measurements, when measuring a short distance,
incline the prism slightly so that the EDM can ignore unnecessary reflections on the
prism surface, as shown below.
Note – Hold the prism securely in place and do not move while taking measurements.
Note – In Prism mode, in order to avoid false measurements on objects other than the
prism or reflector-sheet, targets that are less reflective than the prism or reflector sheet are
not measured. Even if you start a measurement, measured values are not displayed. To
measure less reflective objects, use the N-prism (reflectorless) mode
2.2
Measurement in reflectorless mode
The intensity of the reflection from the target determines the distance the Trimble M3
DR instruments can measure in this mode. The color and condition of the target
surface also affect the measurable distance, even if the targeted objects are the same.
Some less-reflective targets may not be measured.
The following table describes some examples of targets and approximate measureable
distances.
Target
You can measure approximately...
Traffic signs, reflectors
500 meters (1640 feet)
Paper (white), veneer (new)
300 meters (990 feet)
wall (brightly painted), brick
100 to 200 meters (330 to 660 feet)
Measurable distances may be shorter or measurement intervals may be longer in the
following cases:
•
the angle of the laser against the target is small
•
the surface of the target is wet
In direct sunlight, the measurable distance may be shorter. In this case, try to throw a
shadow on the target.
Targets with completely flat surfaces, such as mirrors, cannot be measured unless the
beam and the target are perpendicular to each other.
Note – Make sure there are no obstacles between the instrument and the target when
taking measurents.

Note – When you need to take measurements across a road or a place where vehicles or
other objects are frequently moving, take several measurements to a target for the best
result.

Checking and adjusting the circular level
Once you have checked and adjusted the
electronic level, check the circular level.
If the bubble is not in the center of the level,
use the adjusting pin to rotate the three
adjustment screws of either circular level on
the instrument main body or tribrach until
the bubble is centered.
4.3
Checking and adjusting the laser plummet
The optical axis of the plummet must be aligned with the vertical axis of the
instrument.
To check and adjust the optical/laser plummet:
1.
Place the instrument on the tripod. You do not have to level the instrument.
2.
Place a thick sheet of paper marked with an X on the
ground below the instrument.
While you are looking through the optical plummet, adjust
the leveling screws until the image of the X is in the center
of the reticle mark .
For laser plummet, adjust the laser pointer to the X.
3.
Rotate the alidade 180°.
If the marked image is in the same position in the
center of the reticle mark, no adjustment is
required
For laser plummet, if the laser pointer is on the X,
no adjustment is required.

Checking and Adjustment
Adjusting
There are two steps in the calibration program. Usually you only complete the first step
that is described below, because the trunnion axis is finely adjusted mechanically.
To make a major adjustment to the trunnion axis error compensation, however, you
can complete the second step that is described below and make three sets of
observations.
Note – To set the parameters for trunnion axis error
Second
compensation, establish two targets at a horizontal
target
distance of at least 30 m from the instrument. The
first target should be placed on the horizontal plane
and the second should be more than 30° above the
First
target
horizontal plane. Before you set the trunnion axis
compensation value, you must complete three sets
of F1/F2 observations to these two points. Even if
you complete the second step, the instrument
cannot store a trunnion axis error compensation of
more than 30". If the error is more than 30", the instrument needs a mechanical check.
To enter the calibration program, tap the
Windows button and then select Program /
Calibration.

Checking and Adjustment
Trunnion axis compensation
The trunnion axis error is reported when the vertical axis and the trunnion axis
(horizontal axis) are not perpendicular to each other. The sighting axis error is from
the sighting and the trunnion axes. These two errors can be compensated by applying
the Tr-axis and ACH parameters on this instrument to horizontal angle readings.
ACH
Tr-axis
Because the amount of compensation changes according to the vertical angle, when
compensation is enabled there is a slight movement in horizontal angle even if you
clamp the tangent screw.

Checking the instrument constant
The instrument constant is a numerical value used to automatically correct for the
displacement between the mechanical and electrical centers when measuring
distances. The instrument constant is set by the manufacturer before the instrument is
shipped. However, to ensure the highest operational accuracy, we recommend that you
check the instrument constant several times a year.
To check the instrument constant, you can either compare a correctly measured base
line with the distance measured by the EDM, or follow the procedure below.
P
About 100 m
Q
P
R
Q
To check the instrument constant:
1.
Set up the instrument at Point P, in as flat an area as possible.
2.
Set up a reflector prism at Point Q, 100 m away from Point P. Make sure that you
take the prism constant into account.
3.
Measure the distance between Point P and Point Q (PQ).
4.
Install a reflector prism on the tripod at Point P.
5.
Set up another tripod at Point R, on the line between Point P and Point Q.
6.
Transfer the Trimble M3 DR series instrument to the tripod at Point R.
7.
Measure the distance from Point R to Point P (RP), and from Point R to Point Q
(RQ).
8.
Calculate the difference between the value of PQ and the value of RP + RQ.
9.
Move the Trimble M3 DR series instrument to other points on the line between
Point P and Point Q.
10. Repeat Step 5 through Step 9 ten times or so.
11. Calculate the average of all the differences.
The error range is within 3 mm. If the error is out of range, contact your dealer.

Checking the laser pointer
The Trimble M3 DR series total station uses a red laser beam to a laser pointer. The
laser pointer is coaxial with the line of sight of the telescope. If the instrument is well
adjusted, the red laser pointer coincides with the line of sight. External influences such
as shock or large temperature fluctuations can displace the red laser pointer relative to
the line of sight.
